DIN rail power supply unit DRA480-24
Single-phase input: 90 VAC to 264 VAC
Output: 24 VDC to 71 °C operating temperature
Output power of 480 watts (20 A)
Overload and overvoltage protection
- Single-phase input: 90 VAC to 264 VAC
- Output: 24 VDC to 61 °C
- Output power of 480 watts (20 A)
- Robust metal housing with DIN rail mounting
The DRA480-24 power supply units are high-quality switched-mode power supply units for DIN rail mounting. They impress with their compact and intelligent design as well as their robust metal housing. The output voltage is easy and simple to adjust (22.5 VDC to 28.5 VDC) and is highly stable even with temperature fluctuations and load changes.
In addition to short-circuit protection, overload and overvoltage protection at the output also ensure a high level of safety.
